7 Claims. (01. 106-31) My sheet material is adapted for use as an under heat make the oil sufficiently thin to waterexpansion joint, roofing, floor covering, siding, proof the fiber'without clogging the pores, which etc., and consists primarily of a mixture of ductile would also toughen the fibers and lend greater substances and fibrous matter in varying proporadhesiveness to the fiber in its amalgamation with M V tions and in varying shapes and forms. Ihe the waterproofed binder. For instance, cotton- 60 fibrous material may consist of broom corn, cocoaseed oil might be used, which is a very fluid liquid nut fibre, sisal, excelsior, either in the broad riboil, and it might be desirable to thicken it somebon form or narrow form, in fact any fibrous What to destroy any tendency which might conmatter which can be penetrated by an oily sub-v tinue the fiber in too moist a state. In other 10 stance or a substance which cannot be driven off words, if too thin an oil is used in conjunction 6K readily under a temperature of 250. with certain fibers it may be difiicult to express When fibrous matter is saturated with moisture all of the oil that might be wished to express, and and the mixture is raised to a temperature over if the flow of the oil is regulated, which can be the boiling point of the water, namely 212, the done by sulphur chloride, these liquid and thorlB' fibrous matter losing its moisture content becomes ough saturating tendencies would be more or less 16 brittle and therefore loses its binding strength. regulated.

My invention relates to the treating of this A simple formula would be 10% ribbon exfibrous matter with an oily substance, for instance celsior impregnated with crude cotton seed oil impregnating the same with cotton seed oil and thoroughly pressed between rolls to remove the r 20 then pressing the fibre to remove all surplus oil surplus oil, then mixed with 90% blown asphalt 'so that the actual fibrous matter will only retain having a melting point of approximately 240 and the oily content, and allowing the cells in the apenetration of 32, approximating 19. fibre to be unfilled. Such other substances as This compound is thoroughly mixed, rolled into wood oil, castor oil, glycerine, soap solution or any sheets of various thicknesses for the purpose re- 25 combination of greasy or oily substances which quired. To this formula may be added sulphur will suitably impregnate the material, may be sufiicient to thicken the oily substance under the employed. I find that the impregnation with oil heating process or any other suitable chemical strengthens the fibrous matter the same as water, which would tend to thicken or set the oil in the but is not driven off at low temperatures such as fibre.

The method of preparing resilient construction material, which consists in impregnating fibrous material with an oily substance having the inherent qualities of rendering the material supple, treating the material with sulphur chloride to thicken the oily substance, pressing said material to express a predetermined quantity of said substance to leave the cellular structure of the material unfilled, and thereafter incorporating the treated material with a compressible plastic binder.
